Wow - that's a weird requirement - JUST the initial packets?  TCP is obviously 
way more easy than the others - which I'm not sure how you would consistently 
and accurately do that with sessionless protocols.

What do you mean "find"?  As in capture/store the packets themselves or just 
record the session info?

Ntop / libpcap supports BPF filters, so maybe you could build a filter to only 
capture the packets you want.  Again, not sure how you will accomplish this 
with ICMP and UDP; even with a temporal operative it's unlikely to be very 
accurate.  But I could be wrong, so maybe post your thoughts?

Subject: [Ntop] Packets that initiate connection

I need to find packets that initiate a session (TCP, UDP, ICMP) between pair of 
hosts.  It does not have to be in real time.  Does anybody know if ntop has 
such feature, and if yes, how to do so?  The output I am looking for should 
include hosts' IP/names and port numbers involved in establishing of session.  
I am new to ntop, but have some experience with WireShark.

Thanks, Greg
